Patented Oct. 13, 1914.

To all whom it may concern Be it known that I, EUGENE H. TAYLOR, a. citizen of the United States, residing at Hyde Park, in the county of Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Paper-Box Machines, of which the following is a specification, reference being had therein to the accompanyin drawings.

The mac ine in which my present .invention is embodied operates upon a blank which is scored or moistened on lines extending along opposite side-edges thereof and also ,across opposite ends adjacent the edges of the latter, and which is notched in its opposite side-portions adjacent the ends so as to leave upon the opposite ends of each end-flan e laterally projecting portions forming ben ing-parts. It forms a box or cover by bending the end-flanges linto place and turning the bending-parts of the same around into position at the sides, and bendin the sideanges into place outside the said bendingparts thus positioned, the side-flanges and the bending-parts of the end-lianges being secured together and the desired boxbody or box-cover thereby formed. In the present embodiment of the invention provision is made for the a plication of paste as the securing means, ut the use of other securing means may be provided for in other instances.

The invention includes devices for feeding the blanks in succession by a primary feedmovement from a stack or pile to an intermediate osition where the securing means is applie automaticall to the side-flanges, and then by a secon ary feed-movement from the said intermediate position to the formin -devices, the said feeding-devices prefera lv being constructed and timed so that in the continued working of the machine, as a fresh blank is advanced from the stack or pile to the intermediate fposition, the preceding blank is advanced rom the latter position to the forming devices. As the preferred means of affecting this twostep feed, as it may be called, the invention includes a double feeder, one portion thereof taking the fresh blank from the stack or pile and advancing it to the intermediate position and the other portion advancing the precedin blank from such position to the forming evices.

Thel invention includes, also, improved devices for ejecting the boxes from the inachine.

l'n the drawings,-Figure 1 shows the machine in front elevation. Fig. 2 is an elevation of the machine, looking at the ri t hand end of the latter. Fig. 3 is a p an thereof. Fig. 4 is a view showing the machine in vert1cal section from front to rear in a ,plane located at the middle of the width of the machine. Fig. 5 is a view in horizontal section in the plane of the dotted line 5, 5, of Fig. 1. Fig. 6, Sheet 6, shows the feeder in side elevation. Fig. 7, same sheet, is a plan of the feeder and portions of the guides therefor. Fig. 8, same sheet, is an end elevation of the parts shown in Fig. 7. Fig. 9, Sheet 7, is a partly sectional rear elevation of the presser and corner-turner devices, partly broken away. Fig. 10, same sheet, shows the same in plan. Fi l11, Sheet 6, is a side elevation of one the corner-turners, detached. '12, same sheet, is a plan of the said corner-turner. Fig. 13, same sheet, is an end elevation thereof. Fig. 14, Sheet 5, is a plan view of one of the lanks which are operated upon by my machine.

A blank such as the illustrated machine is designed to operate upon is shown at A, Fig. 14, Sheet 5, the side-scorings or lines of moistening being indicated at a, a, the endscorings or lines of moistenin at b, b, the notches at c, c, etc., and at d, etc., are the bending-parts of the end-fianges- The main arts of the frame of the machine are the ase 1, the opposite side-frames 2, 2, rising from the said base, the table 3 mounted upon thek tops of the said sideframes, the pillars 4, 4, upon the said table, arranged in pairs at the opposite sides of the machine, and the head 5 upon the table between the two airs of pillars. The driving shaft 6 extend; crosswise of the machine and is supported in bearin which are provided in connection with t e side-frames 2, 2, at a convenient height in the machine. At 7, Figs. 1, 2, and 5 is a band-pulley, loose upon the said shaft designed to receive 'a suitable driving-band' (not shown) by means clutched to the shaft.

of which it is to be rotated. At 8 is a clutch-hub upon shaft 6, by means of which band-pulley 7 may be made fast with the shaft in ordinary manner when it is desired that the machine shall operate, at 9 a clutchfork engaging with a grooved portion of the said huh indicated in Fig. 5, at 10 a rock shaft on which clutch-fork 9 is made fast, and at 11 an operating or shipper-handle on the forward end of the rockshaft for operating the clutch devices by hand to connect and disconnect the driving-power. At 12, Figs. 1. 2 and 5 are braking devices of well-known character arranged to act in connection with the driving-shaft 6 and operated as usual by the clutch-controlling devices already described to quickly arrest the machine when the band-pulley 7 is unclutched from shaft 6, and to release the said shaft when the said band-pulley is At 13, Figs. 4 and 5, is a spur-pinion fast on the driving-shaft 6 and meshing with a spur-gear 14 fast upon the main shaft 15, extending crosswise of the machine and mounted in bearings which are provided in connection with side-frames Q, Q. Shaft 15 carries the camsby means of which the required movements of the various working parts are caused.

The hopper for containing the stack or pile of blanks is located in the upper part of the machine, at the rear thereof, above the table 3. The pasting devices are located neXt in front of the hopper, and the forming devices are arranged in front of the pasting devices. The feeder is arranged above the table and Works beneath the hopper and pasting devices, it acting by one forward stroke thereof to transfer a blank from the bottom of the stack or pile in the hopper into position in connection with the pasting devices to receive paste upon the side-flanges, and at the same time move a previous blank which has had paste applied thereto by the sa id devices forward from the latter and deliver it in position to be acted upon b v the forming devices.

The hopper comprises, essentially, the opposite side-guides 16, 16, Figs. 2, 3, 4, the back-guides 17, 17, Figs. 3 and 4, mounted upon the said side-guides, and the frontgage 18, Figs. 3 and.4. The side-guides 16, 16, respectively, are supported at their rear ends by the cross-shaft 19, Figs. 2, 3, 4, which in turn is mounted in bearings' in uprights 20, 20, Figs. 2 and 3, rising from table 3. Forward extensions 21, 21, Figs. 1, 3, 4, of the said side-guides are supported by a cross-shaft 22 at the front of the machine, the latter cross-shaft being mounted in bearings with which stands 23, 23, Figs. 1, Q, 3, extending forward from pillars 4, 4, are provided. The side-guides 16, 16, as is customary, are adjustable toward and from each other to suit the length of the blanks which it is desired to use. For the purposes of the adjustment the front and rear shafts 22, 19, are each formed with right-and-left screw-threads as vshown in the drawings, and the opposite ends of the respective sideguides are furnished with nuts fitting the corresponding screw-threaded portions of the said shafts, so that upon siniultaneoushY rotating the two shafts in the proper directions the side-guides may be shifted bodily toward and from each other. The two shafts 2Q, 19, are connected together so as to cause them to turn in unison by means of a side-shaft 24, Figs. 1 and 3, mounted in bearings in fixed stands 241, Q41, Fig. 3, and provided with bevel-pinions 25, 25. Fig. 3, meshing with bevel-gears 26, Q6, fast on the shafts Q2, 19. For convenience in making the adjustment by hand, the side-shaft 24 has fixed upon its front end an operating crank-handle Q7. Figs. 1, 3, 4. The rear corners of the blanks in the stack or pile contained within the hopper engage with the back-gaiides 17, 17. To suit variations in the widths of the blanks in the direction from front to rear in the machine. the backguides are made adjustable in such direction. toward and from the front-gage. This adjustability is secured vhy furnishing each back-guide with a piece :'28, Fig. 4, fitting a slot 99, Figs. 2 and 4, extending horizontally along the corresponding side-guide, and by clamping the said piece at the required point in the length of the said slot by means of small boltsl 30,A 30. Fig. 2, having washersl applied between their heads and the outer surface of the side-guide. Frontgage 18, Fig. 4, is applied to a support 31'. Fig. 4, carried by the rearward extension 32 of a casting 33 carried by head 5 of the machine-frame, and is provided as usual with a set-screw 34 by means of which to adjust the same vertically to vary the height of its lower end above the upper surface of the feeder to suit the thickness of the blanks in use at any given time.

The feeder, shown separately in Figs. (3, 7, 3, Sheet 6` comprises the feeder-body 35. feeder-slide 36. and lateral blank-supports 37,37. The feeder-body has'opposite bars 33,33, extending parallel with each other from the rear of the machine toward the front thereof, and upon .which the blank to be fed rests as customary in the like cases, the said bars being provided with blank-engaging shoulders 39, 39, as usual, for engagement with the rear edge ofr the bottom blank of the stack or pile when the feeder moves forward from its rearwardly retracted position shown in Figs. 3 and 4, to push such blank forward past the lower end of the front-gage 18. The said bars are provided, in addition, with a second set of blank-engaging shoulders 40, 40. at a distance forward of the first set some- The shaft 74 has combined therewith means for rotating the same and the said'roll 0r rolls for the purpose of constantly presenting freshly-charged surfaces of the said roll or rolls in position above the pan. The rotating means comprises a grooved bandulley 78, Figs. 2 and 3, fast upon the shaft 4, and an endless driving-band 79, Figs. 1, 2, 3, 4, 5, passing around the said bandpulley, a rotating cross-shaft 80, Figs. 2, 4, 5, in the lower part of the machine at the rear of the latter, mounted in bearings supported by the side-frames 2, 2, and a grooved pulley 81 fast on the said crossshaft and around which the said drivingband passes also. Thesaid cross-shaft 80 is rotated from the main shaft 15 by means of a grooved pulley 82, Figs. 2 and 5, fast on the cross-shaft, a driving-band 83 and a grooved band-pulley 84, Fig. 1, fast on the shaft 15. The carriers 77, 77 at the opposite sides of the machine have combined therewith operating connections comprising at each side a swinging arm 85 fast upon a rcckshaft 86 supported by stands 87, 87, attached to the corresponding side-frame, to which rockshaft the said arm is fixed. The rcckshafts and arms at the opposite sides of the machine are connected to move in unison. but oppcsitely with respect to each other, by means of arms 88, 89, which are fixed to the respective rcckshafts, and a connecting-rod 90 joining the said arms with each other. The arm 88 extends upwardly from its rockshaft while the arm 89 extends downwardly from the rockshaft on which it is mounted, and this causes the rockshafts to turn simultaneously but in opposite directions. ()ne of the said rock-shafts is operatively combined with the main shaft 15 by means of aurai-m 91 fixed thereon, a connecting rod 92 joined at its upper end to the arm 91, a rocker or rocking lever 93 mounted on the cross-shaft 69 but turning freely thereon. and a cam-groove in the cam-disk 71 fast on shaft 15, the rearwardly-projecting arm of the rocker or rocking lever 93 having the lower end of 'connecting-rod 92 pivotally joined thereto,

and the forwardly-projecting arm thereof being provided with a roll or pin which enters a cam-groove in the said cam-disk 71 at the side of the latter opposite that containing the cam-groove for producing the vertical movements of the pasters. As the shaft 15 and the said cam-disk rotate, the carriers 77 77, and the transferring pasterolls carried thereby are caused to reciprocate toward and from the pasters. Carriers 77, 77, rest upon suitable guides, over which they slide in their movements.

A blank which by one advancin movement of the feeder is fed forward rom the bottom of the stack or pile in the hopper in consequence of the engagement of the rear set of shoulders 39, 39, of the feeder with the rear edge of such blank, is located by the completion of the said advancing movement in position beneath the pasters, and remains t ere while the feeder recedes to its starting position, and is there acted upon by the pasters, which apply paste to the sidefianges at c', c, etc., Fig. 14, Sheet 5. In the next advance bf the feeder, causing its shoulders 39, 39, to engage another blank, and advance the latter from the hopper to the intermediate position, the forward set of shoulders 40, 40, engage with the pasted blank and advance it from the intermediate position into position between the formingblock and follower. In being thus advanced, the pasted blank is guided through the engagement with its ends of the guides 21, 21, constituting extensions of the side-guides 16, 16, of the hopper, and being in consequence adjusted in unison therewith. The forming-block 94 and follower 95, between which the pasted blank is fed by the feeder in the manner just explained are shown best in Fig. 4. In the present instance the forming-block is arranged above and the follower below, but this precise arrangement is not necessar in all embodiments of the invention. T e forming-block is attached to the lower end of a slide-rod 96, working in guides in the casting 33. It is operated through connections with the main shaft 15, comprising a collar 97 fast on slide-rod 96, a link 98 having one end thereof connected pivotally t0 the said collar and the other end thereof connected pivotally to an arm 99 projecting forward from the inner end of a rockshaft 100 upon which it is fast, the said rockshaft being mounted in bearings in the .said casting 33 and in a stand `101 rising from the pillars 4, 4, at the left-hand' end of the machine, and having fixed upon its outer end a forwardly-projecting arm 102 to which is connected pivotally the upper end of a connecting-rod 103, the latter having its lower end connected pivotally to an arm 104 projectin forward from the outer end of a rocksha t 105 ,in the lower part of the machine, supported in a bearing with which the left-hand-side-frame is provided, the said rockshaft having fixed upon its inner end a forwardly-projecting arm 106 carrying a pin or roll which works in the camgroove of a cam-disk 107 fast u on shaft 15. The follower 95 is attached to the upper end of a slide-rod 108 working in guides in the casting 109 depending from the table 3 at the front of the machine. It is o erated through connections with the main s aft 15 comprising a collar 110 fixed upon the sliderod 108, a link 111 having one end thereof connected pivotally to the said collar, a lever 112 pivoted at 113 upon the rear portion of the said casting and having the other end of the said link connected pivotally to its forward arm, aconnecting-rod 114 havingits upper end connected pivotally with the rearwardly-projecting arm ofthe said lever, a lever 115`mounted loosely upon nthe rockshaft 105, and havingv the lower endo'f'the said connectingrod joined pivotally to its rearwardly-projecting arm, and with its forwardly-projecting arm provided with ya pin or roll working in acani-groove formed in one Side of the cam-disk 107fast upon the shaft 15. By the vrotation of the said shaft and the cam-diskr 1 O7,the latter acts through the intermediate trains'` of mechanism which have beendescribed tol cause the formingblock, or, as it may aiso be termed, the former, to moveagainstthe blank and press the latter againstA the follower, the formingblock andffollowerthen moving in`unison into position between the/devices for turning the sideV and end flanges and pressing them into place, and subsequently returning in unisonfuntil they have cleared the said devices, after which lthe forming-block byy its greater extent ofiinovement separates.

from the follower soas to release the box which has .been produced by ,the operation of the machineMthe vforming-block with.- drawing from the'said box, and leaving it resftingupon the `to 3 `ofthe follower. The

forming block and ollower are actuated. by separate'fcanis (inthisV instancethe tvvoV cam,-y grooves which havebeen described), one for each, and they movements vary in length and time,j`whfi`ch' israde'possible by' the useof separate cams, buth While the 'forming block' and follower are together they movek in unison., l v, v.

Adjacent they forming devices areblocated y the flange-turning, corner-turning, v and pressing devices." These comprise 'oppo'` sitely-disposedl end-pressers 116,116, Figs, 9v and 10.

The four pressers encirclethe normalposi'tion of the follower,as`shown Fig. 4, and are so adjusted'that in their normal position they shallfit closely around ther exterior of the" ,forming-block inthe fde. pressed vposit-io'n oflv the latter. VIn op,-v eration, Aas the forming-block andvfollower descendin unison,` with a Vblank clamped yin position between them, andlwith the flanges of the blank projecting at four' sides.` and as theforining-block presses the central portion of the blankdown Awithin the groupvof vpressers,J the end andv side-flanges are turned upward against the sides of Vthe forming-blo ck.,v The top portions of the endpressers 116,V 11G, arehigher than those of the side-pressers and'fconsequently act to turnthe end-,flangesof the blankin first against the ends of the forming-block. The former and follower thendwelllong enough to permit thecorner-turners to act. Movement of the corner-tumors 118, 118, inward alongside the forming-block turns the bending-parts d, d, etc., Fig. 14, Sheet 5, of the blank around against the sides of the forming-block. The forming-block and follower then descend farther, `so th atthe side-lianges of the blank are turned by the side-pr'essers inward toward the forming-block outside the corner-turners and the turned-around bending-parts, so that when the cornerturners are withdrawn and the pressure of the presser-devices is "applied such Asidefia nges shall be caused toadheie to the bendingfparts of the end-flanges#y I Each endpresser comprises a carrier 119, Figs. 1, 9, and 10, Sheet 7, which is littedto a fixed guide 120, Figs. 2, 3, 9, 10, to slide lengthwise therein toward and from the ad-v jacent end of the forming-block. The inner end of this carrier is formed with an up` wardly-extended portion forming a backing .for the `holder of the end-,plate 121 whichv orplate 123 is secured to the lower edge of the block or plate 122 by a 'screw 126, and its opposite,4 ends project at opposite sides of the said block 'orb plate, one end extending outward beneath the inner end ofthe carrierv 1,19, and the other'end projectinginward to constitute aprest and support forthe'endplate 121. This latter end'carries a pin or projection 127 entering .the bottom edge of the blocker plate tokeep thesam e vinA place.

To the upper edge ofthe end'fplate is se cured the inner end oft-he top, strip' 128 by ra screwf129, the said plate-projecting out-v ward over the tops of the block o r plate 122 and the enlarged inner end ofthe carrier and resting thereon, and being provided with a projection or pinl() which enters a holein the top of the block'or plate 122 to assist in` keeping'the end-plate in place. For the actuation of the end-pressersashcrt shaft 131 is Amountedl in fixed bearings at each end of the forming devices. This shaft isfurnished with an eccentric 132 which is surrounded byan eccentric strap 133 having the rod-portion thereof pivotally connected with a stud `134'on a carriage'l which is connected with thecorresponding 'Carrier 119.v The connection is established by Ineens of a right-and-left' 'screw 136 hav ing one threaded portion thereof engaged with the carrier and the other with the car` riage. When the eccentric is rotated, movement transversely of the machine 1s communicated to the end-presser. For the purpose' of operating the eccentrics at the proper times in the working of the machine to produce the required movements of the two endpressers, each shaft 131 is operatively combined with main shaft 15 by connections comprising a spur-pinion 137 fixed upon such shaft, a vertical rack 138 meshing with the said spur-pinion, an upright rod or bar 139, Figs. 1 and 2, to the upper endl of which the said rack is attached, a yoke 140 attached to the lower end of such rod or bar, and a Cam-disk 141 fast on shaft 15 and having a cam-groove (shown by dotted lines in Fig. 2) receiving a pin or roll carried by the said yoke. By the rotation of shaft 15 and cam 141 the yoke, rod or bar, and rack, are moved up and down, and thereby the pinion and eccentric are rotated, first in one direction to move the end-presser inward to perform its work of pressing an end-fiange, and then outward to return the same to its normal position. By constructing the end-presser with the carrier'and carriage, and'connecting them in adjustable manner by means of the right-and-left screw, provision is made for 'convenient adjustment of the endpresser to suit the length of forming-block employed, according to the size of box being m'ade. v

The side-pressers 117,117, have longitudinal acting portions to press against the sideflanges of the blank in forming a box, and have end-extensions which have openings within which are fitted sleeve-like nuts 142, 142, etc. The short shafts 131, 131, have right-and-left screw-threaded portions upon which the said nuts are mounted. Conseuently, when the said' shafts are rotated by t Y e means which hasalready been explained the side-,pressersare drawn together so as to press the side-flanges of a box toward the forming-block, or are moved apart so as to relievel the pressure and open them away from the finished box. For the purpose of enabling the side-pressers to be adjusted nearer together or farther apart to suit the size of box desired to be made, -and enable different sizes to be made, the sleeve-like nuts 142, 142,-are adapted to be rotated manually when vdesired upon the screw-threaded portiens of the shafts 131, 131. To this end, each nut is furnished with a worm-gear 143, and the two nuts pertaining to the opposite ends of each side-presser are engaged by worms V144, '144, upon a shaft 145 which is mounted in bearings at 146, 146, upon such side-presser', and-provided with squared ends for the reception of 'a' socket-wrench or key for convenience in turninvr the same by hand in making adjustments. ither side-presser may be adjusted independently tothe required extent.

The corner-turners 118, 118, are mounted upon the side-pressers, at or adjacent the ends of the latter, and are fitted upon the side-pressers with capacity to slide lengthwise thereof. The body-portion 147, Figs. 11, 12, 13, Sheet 6, of each corner-turner is formed at its bottom edge with a laterally projecting flange, and the iianged portion is fitted within a longitudinal undercut groove in the upper edge of the corresponding side-presser, as indicated in Figs. 9 and 10, Sheet 7. The acting portion of each corner-turner is formed of a piece, Figs. 11, 12, 13, of elastic strip-material projecting from the inner end of the body 147. For the actuation of the corner-,turners at the proper times in the working of the machine, the body-portion of each thereof is formed with a series of teeth, as shown in Figs. 9 to 12, and with the teeth of the two corner-turners at each side of the machine are engaged pinions 149, 149, fixed upon a short shaft 150 which is j ournaled in bearings carried on the outer side of the correspondingl side-guide 21. Each shaft 150 has vfixed thereon an arm 151, 'to which latter is connected one end of a link 152 having its other end connected to an arm 153 that is splined upon a rod 154 extending" crosswise of the machine and supported in bearings provided or formed in connection with the front illars 4, 4. Arm 153 is engaged with the adDjacent side-guide 21 so as to cause said arm to accompany the side-guide as the latter is adjusted cross-wise ofthe machine. Rod 154 has fixed upon the left-hand end thereof an arm 1541 to whichl is pivotally joined the upper end of a connecting rod 155 having its lower end connectedV pivotally with an arm 156 fixed on the outer end of a rock shaft 157 that is mounted in a bearing rovided in connection with the left-hand side-frame 2, the said rock shaft having fixed upon its inner end a forwardly-projecting arm 158 to which is connected pivotally the upper end of a connecting-rod 159, the lower end of which is connected with arm 160 hung loosely upon cross shaft"J 105 and carrying a roll or pin which works in a cam-groove formed in one side of the gear 14 on shaft 15.A By the rotation of the said shaft and gear movement is communicated through the intermediate mechanism to the rod 154 to rock the latter, and through the connections described between the said rod 154` and the short shafts 150, 150, the latter are rocked so as, through the engagement of their pinions 149, 149, with the teeth of the corner-turners to move the latter inward along the side-pressers at the pro er time to engage with the bendingparts oi) the end-flanges of a blank which is being operated upon, to turn such bendingarts inward against the sides of the formm -block, and afterward outward along the si e-pressers toereturn them to their normal positions. It will be apparent that when the side-guides 21, 21, are adjusted crosswise of the machine in the manner `already explained, the corner-turners are shifted inward or outward, as the case may be, upon the sde-pressers `in consequence of the en gagement of the teeth ofthe corner-turners with the pinions of the short shafts 150, 150, the latter being carried by the side-guides as already explained. Consequently, the con- Anections just referred to secure conjoint adjustment of the side-guides and cornerturners to suit the size of blanks employed. Boxes vary from one another inthe depth of their flanges. To provide for variations in this respect, the corner-turners are made adjustable relative to the side-guides 21, 21, in order that after the adjustment of the said side-guides to suit the length of blank' the corner-turners may be set or adjusted inward or outward as the case may be into ro er workin relations v.y ith the ends. of P P the forming b ook that is employed. To this end, the arm 151 of each shaft 150 is formed with a s lit socket as shown in Fig. 9 to lit the sha t, and is providedl with a screw as shown to clamp it frictionally upon the shaft. On loosening the screw, the shaft may be turned independently of thearm in adjusting the corner turners in or out, after which the screw will be tightened again. Pinions 149, 149, are anged to lit on opposite sides of the toothed portions of the corner-turners, so rthat when the side-pressers are adjusted or moved toward or from each other the said inions, which are splined upon their sha ts 150, 150, accompany the side-pressers and corner-turners.

The corner-turners normally occupy a rctractedjposition adjacent the endpressers.

As soon as the end-ilanges have been bentk against the ends 'of the formi -block by their encounter with the upper ggges of the end-pressers, the corner-tumors are moved inward len hwiseof the side-pressers, their acting en s engaging with the bendingparts or lips of the end-anges othe'blank and operating to bend the said ortions of the blank around the corners ofp the forming-block into place a ainst the sides of the forming-block. By 't e encounter of the side-Han es of the blank with the upper edges o the side-pressers the side-flanges are bent upward into lace at the sides of the forming-block outside the bendin parts or lips and the oorner-turners' whic hold the said bending-parts or lips in place. The continued descent of the forming-block and follower carries the flanges of the box downward awayl from the corner-turners, thus rmitting the end-portions of the sideanges to make contact with the pasted portions f the 'bending-parts or lips. The actuating devices of the corner-turners are timed to cause these latter to remain in their working position, holding the bending-parts Y or lips of the blank against the sides of the forming block, while the side-fiangcs are being turned up into place outside and against the corner-turners, and until b the descending movement of the forminglock and follower the side-flanges have been drawn downward clear of the corner-turners and have been allowed to close completely against the bending-parts or lips. To permit this mode of operation, without removal or collection of paste from the side-flanges by the corner-turners, the workin part of each of the latter is formed wit an out-turned knife-edge, as y, Figs. 11, 12 and 13, Sheet 6. The flat back of the corner-turner presses against the bending-part or lip and holds the latter in place while the side-flange is turned in against this knife-edge, which holds the pasted portion of the side-flange for the time being from contact with. the bending-part or lip. As the forming-block continues its descent, the side-iange draws downward along the knife-edge, and finally on clearing the same is permitted to enter into full contact with the bendin -part or lip and adhere to the latter. T e knifeedge does not remove or collect paste. It prevents the side-flanges from striking forcibly 'and suddenly against the adjacent surfaces so as to sputter the 1caste which such flange carries. It also renders it feasible to cause the corner-turner to remain in working position, holding the bending-part or lip in place. If the bending-part or lip were not thus held, it might assume an outward flarin position in whichtheV inwardly swinging side-Hange would contact with it so as to kbecome stuck thereto, forcing the bending-part or lip to assume an improper position. The outturned knife-edge of the corner-turner slopes from the upper edge thereof to the lower so as to allow the side- Han e to close in gradually against the ben ing-part or lip.

In the rising movement of the formingblock 154, after it has begun to separate from the follower the box 1s stripped from the same by means of strippers 161, 161, located at opposite ends of the formingblock and'extending down from the head 5 by which the same are carried. The completed box, supported by the top surface of the follower 95, is pushed forward out of the machine b means of reciprocating ejectors 162, 162, ig. 1, carried by arms 163, 163, projecting inward from rods 164, 164, Figs. 1, r2, 3, lsupported in guides 1641, 1641, Fig. 3, carried by hopper sides `16, 16, at opposite sides of the machine and extending from front to' rear. The said rods are operated to cause the ejectors to act at the required time in the working of the machine through connections between the same and the main shaft 15, such connections comprising links 165, 165, Figs. 2 and 3, connec'ed with! blocks 166, 106, Fig. l, upon the respective l rods, arms 10T, 16T. Figs. 2, 4 and 5, at` oppcsite sides of the machine'and with the l upper ends of which the said links are also connected, .a epass-shaft 168 mounted in bearings with which the side-frames 2, 2, are provided at the rear of the machine, and upon which cross-shaft the said arms are fixed, a third arm. 169, fast upon the crossshaft 1118, a connecting-rod 1T() having its rear cud pivotally connected with the said arm 169. a lever 171, Fig. 1, mounted loosely upon cross-shaft 139 and having the forward end of the said connecting-end joined pivotally to its upwardly-extending arm, the forwardly-projecting arm of lever 171 being provided with a roll or pin which works in a cam-groove formed in one side of camdisk 54. By the rotation of shaft 15 and the said cam-disk, movement is transmitted through the intermediate mechanism which has been described to the rods 164, 164, and the ejectors carried thereby. The ejecting devices just described act squarely against the rear side of the completed 'box at or near each end of the latter and push the said box squarely out of the machine. Swinging cjectors such as heretofore have been employed in some cases are objectionable because they sometimes act to turn the boxes around without completely discharging the latter from the machine in which they are employed.

The transversely adjustable supports 3T. 37, which are connected with the feeder act frictionally upon the blank which is supported and being' advanced by the feeder to hold back such blank against the feeding shoulders 39, 39. They also serve to support the outer portions of the blank under the pressure of the pasters thereagainst in applying paste to the side-flanges at c, 0, Fig. 14, Sheet In the illustrated machine, the parts are timed so that after theflanges of the boxblank and the bending-parts or lips thereof have been turned or bent into their respective places, the end-pressers close in and act against the end-franges of the box` slightly in advance of the application of pressure by the side-pressers against the side-flanges. and they maintain their pressure upon the end-flanges while the pressure of the side-pressers against the side-flanges continues. Thereby I insure that the endflanges and their bending-parts or lips shall be in proper position when the side-flanges are closed against the said bending-parts or lips, and shall be maintained in such position until the side-flanges have been united to the bending-parts or lips. This order of precedence in the timing of the action of the end-,pressers is attained in the present instance by the fact that the eccentrics 132, 132, arrive at center so as to complete the inward movement of the end-pressers before the screw-threaded shafts 131. 131, complete the inward movement of the side-pressers. 'I he continuance of the pressure of the cnd-pressers while the side-pressers are completing their inward movement is due to the fact that the eccentrics are so arranged and related that as such inward movement of the side-pressers is nearing completionA the eccentrics shall slightly pass center. The end-pressers practically dwell in their innermost positionias the eccentrics approach and slightly pass center, particularly if there is a trifle of play in the connections between the eccentrics and the endpressers. The maintenance of substantially uniform pressure by the end-pressers is aided by the elastic cushions 124, 121, which subserve this function in addition to that of accommodating slight variations in the thickness of the box-blanks which are operated upon. Cushions may be employed in connection with the side-pressers if deemed desirable, but ordinarily the torsion of the screw-shafts 109, 109, will be sufficient to allow the side-pressers to yield to the necessary extent.
